When to Harvest Butternut Squash

Knowing when to harvest butternut squash is essential for getting the best flavor, texture, and nutritional benefits from this delicious winter squash. Harvesting too early or too late can affect its quality and storage life.

In this guide, we’ll walk you through everything you need to know about when to harvest butternut squash and share some useful tips to ensure your garden yields a healthy and plentiful crop.

Understanding The Growth Cycle

Butternut squash is a type of winter squash that typically takes between 85 to 110 days to mature after planting. The growth cycle begins with planting the seeds in spring, and the squash will develop over the summer before reaching full ripeness in late summer to early fall.

Butternut squash thrives in warm weather, but as a winter squash, it’s harvested in the fall after the skin has thickened and hardened. Properly understanding its growth cycle will help you plan the best time to harvest.

Signs That Butternut Squash is Ready to Harvest

Knowing the exact signs that your butternut squash is ripe is key to harvesting at the perfect time. Here are some indicators that your squash is ready:

Skin Color and Texture

One of the most obvious signs that butternut squash is ready to harvest is its skin color and texture. A fully mature butternut squash will have a rich, deep tan or beige color. The skin should be hard and difficult to puncture with your fingernail. If the skin is still green or soft, the squash needs more time to ripen.

Stem Changes

Check the stem of the butternut squash for ripeness. The stem will begin to dry out and turn brown and woody as the squash matures. A green and soft stem indicates that the squash isn’t ready yet. Ideally, the stem should be dry and firm, but not brittle or breaking off easily.

The Sound Test

Another simple way to check if your butternut squash is ready for harvest is the sound test. Gently tap the squash with your fingers. If it produces a hollow sound, it's likely mature and ready for harvest. If it sounds dull or solid, it may need more time on the vine.

Best Time of Year to Harvest

Butternut squash is typically harvested in late September through October. It’s best to wait until the squash has had time to fully ripen before the first frost, as frost can damage the plant and affect the quality of the squash.

Keep an eye on the weather forecast, and aim to harvest before the temperature drops below freezing. Squash that ripens in cooler autumn temperatures often has better flavor and can be stored longer.

How to Harvest Butternut Squash

Harvesting butternut squash is straightforward, but it’s important to do it carefully to avoid damaging the squash or the vine. Here’s a step-by-step guide:

Use sharp pruning shears or a knife to cut the squash from the vine. Don’t pull or twist the squash, as this can damage the fruit or the plant.
Leave a 2-3 inch stem attached to the squash. This helps the squash store better and prevents rot.
Handle the squash gently to avoid bruising. Even though the skin is hard, bruises can reduce the storage life of the squash.

Once you’ve harvested your butternut squash, allow it to cure in the sun for 10-14 days if possible. Curing helps harden the skin even further, which improves its storage life and flavor.

Tips for Long Term Storing After Harvest

Proper storage is key to making your butternut squash last through the winter months. Follow these tips for optimal storage:

Store in a cool, dry place: The ideal storage temperature is between 50°F and 60°F. A basement, pantry, or unheated closet can be good storage locations.
Avoid refrigeration: Cold temperatures can cause the squash to spoil more quickly. Only refrigerate cut or cooked squash.
Check for signs of rot: Regularly inspect your stored squash for any signs of soft spots or mold. Remove any damaged squash immediately to prevent it from affecting others.
Keep them elevated: Store the squash on a shelf or rack rather than on the floor to allow for airflow and prevent moisture buildup.

When stored properly, butternut squash can last up to 3-6 months, making it a great vegetable to enjoy throughout the winter.

Common Mistakes to Avoid When Harvesting

To ensure your harvest is as bountiful as possible, avoid these common mistakes:

Harvesting too early: If you harvest too soon, the squash will lack flavor and may not store well. Wait until the skin is fully hard and the stem has dried out.
Leaving squash on the vine too long: While you want the squash to ripen fully, leaving it on the vine for too long, especially in freezing conditions, can lead to damaged fruit.
Breaking the stem: Always leave part of the stem attached to your squash for better storage.
Not curing the squash: Skipping the curing process can reduce the shelf life and sweetness of your butternut squash.

My Final Thoughts

Knowing exactly when to harvest butternut squash ensures that you’ll get the best flavor, texture, and storage life from your crop. By paying attention to the color, stem, and overall health of the squash, you can make sure you’re picking at the perfect time.

After harvesting, follow proper storage methods to enjoy your butternut squash for months to come.
